About this Manual
This manual covers the installation, operation, and conguration of the Extron 
PVS 204SA PoleVault
™
 Switcher. Throughout the manual, this switcher is 
interchangeably referred to as the PVS 204SA, PVS switcher, PoleVault switcher, 
PVS, and switcher.
About the PVS 204SA
The Extron PVS 204SA is a four input, two output, twisted pair, audio and video 
switcher with a built in audio amplifier. This switcher is comprised of two 
independent, built in switchers (a 2 x 1 RGB video and audio switcher and a 2x1 
composite video and audio switcher), that allows the PVS 204SA to accept high 
resolution (RGB) video and audio, and composite video and audio signal inputs, 
along with a line level mono audio auxiliary/mix input. The PVS 204SA is part 
of the PoleVault System, a cost effective system with easy cable installation for 
transmission of video and audio signals, that is used in conjunction with the Extron 
PVT series of transmitters and Extron speakers.
The PVS 204SA can be easily installed at ceiling level using the Extron Pole Mount 
Kit (PMK 450) as part of the Extron PoleVault system.
The PVS switcher receives the video and audio signals sent from PVT transmitters, 
which can be located up to 100' (30 m) away. The signals can be sent over Extron 
Enhanced Skew-Free
™
 A/V UTP cable, or any CAT 5, 5e, or 6 shielded twisted pair 
(STP), unsheilded twisted pair (UTP), or foil shielded twisted pair (FTP) cable.
The PVS switcher can be controlled from either the front panel buttons, an RS-232 
control, an IR remote, or a MediaLink controller. 
The PVS 204SA’s built-in 2-channel power amplier outputs up to 13 W on 4 ohm 
load per channel or 7 W with 8 ohm loads as stereo or dual mono audio. Volume 
control is made via the front panel, RS-232 , IR, or an Extron VCM control. 
Various front panel controls allow the user to adjust the Aux/Mix volume 
(independent from input gains, power amplifier gain, and volume) and global 
control of the power amp level adjustments.
RS-232 control allows the user to adjust the individual channel gain, limiter on/off 
settings, loudness on/off settings, and bass and treble adjustments. 
A dual DIP switch allows the user to switch between stereo and dual mono mode 
outputs, and to switch the high pass filter on or off.
TP cable advantages
Twisted pair cable is smaller, lighter, more flexible, and less expensive than 
coaxial cable. Termination of TP cable with RJ-45 connectors is simple, quick, and 
economical. See chapter 2, “Installation”, “A/V input connections” section, for 
wiring details.
